Specification of Letters Patent. Patented Apr. 20, 1920.

Application filed August 1, 1916. Serial No. 112,599.

T all whom it may concern:

Be it known that 1, CHARLES H. HOWARD, a citizen of the United States, residing at Saugus, Massachusetts, have'invented an Improvement in Paper-Reinforcing Machines, of which the following description, in connection, with the accompanying drawings, is "a specification, like characters on the drawings representing likeparts.

The invention to be hereinafter described relates to machines for reinforcing fabrics, and more particularly to that type of such machines wherein paper or similar material is strengthened or reinforced by means of transversely extending filaments such as threads, tapes, or other strengthening strips.

Various attempts have been made heretofore to provide a machine to carry out this count-of the necessary weight of the rotary means employed together with theload carried and the necessity for interposition of a transferring means between the material to This be reinforced and the rotary means.

. necessity for transferring the threads from the rotary means .to the material to be reinforced has also necessitated complication in the mechanical means employed and has introduced unreliable action in the operation of the mechanisms. \Vhere the prior attempts have used individual reciprocating devices or shuttles for introducing the transverse reinforcing threads, the operation of the machines have been necessarily slow with the result of increased cost in production.

WVith these and other considerations in view, one ofthe important features of the present invention is to provide means for drawing the threads or other reinforcing filaments successively from a source of-supply and conveying them transversely for direct delivery to the material to be reinforced. By this manner of introducing the transversely extending reinforcing filaments the me hanical problems are simplified, rapidity of production results and reliability in the uniformity of product produced is insured.

Another important feature of the present invention consists in a series of'arins which are successively and progressively moved in a direction transversely of the material to be reinforced, to distend the reinforcing filaments successively in a transverse direction and deliver such transversely distended filaments one after the other in succession to and upon the material to be reinforced.

Various other important features of the invention will be hereinafter described as well as those referred to and then the various novel features: of the invention will be definitely pointed out in the claims.

In the accompanying drawings is illustrated a good practical form of the invention but it will be understood of course, that the invention is not necessarily restricted to the particulars and details shown, as these may be varlously changed within the true scope of the invention and pointed out by the claims.

As hereinbefore noted the primary purpose of the present invention is to reinforce a fabric such as paper by means of transversely extending reinforcing filaments delivered directly thereto from a rotary and transversely moving member or element, but it is within the purport of the present invention to also introduce longitudinally extending reinforcing filaments and, if desired, to inclose the reinforcing filaments, whether transversely or longitudinally extending, or both, between two superposed pl7i}es or webs of paper or other fabric.

ether a single web of material is to be reinforced or two of such fabrics or webs and to have interposed between them the reinforcing filaments, it is usually desirable to provide one of the surfaces of the fabric to be reinforced with an adhesive to which the transversely extending reinforcing filaments are directly delivered from the rotary drawing means.

This adhesive surface may of course, be applied to the paper or fabric as it is being fed to reinforclng position or it may have been previously applied and then made adhesive by dampening as it is fed directly from a source of supply such as a roll or if desired directly froma paper making machine.

Referring to the drawings, there is mounted between the stands 1 rising from suitable base 2 a support 3 for sustaining the main portions of the rotated filament drawing means. In the present instance of the invention the support 3 consists of a tubular member suitably secured to the stands 1, and

stationary therewith, but it is obvieqls that the support for the moving parts to be de scribed may be otherwise contrived.

Extending longitudinally relative to .the

support 3 and preferably within the same,

is a shaft 4 having at one end thereof and fixed thereto a pulley 5 about which extends the belt 6 from a driving pulley 7 secured to a driving shaft 8.

The driving shaft 8 may be actuated from any suitable source of power and as here shown it is turned bywmeans of belt 9 and pulley 10 which is secured to the shaft 8 substantially as shown in Fig. 1.

, The shaft 4 provides a convenient means for driving the rotary member or members .but as herein indicated,

by which the reinforcing filaments are drawn from'a source of supply in successive order and delivered directly to the surface v prises a series of disks 11, which may be secured to a hub 12, mounted to rotate upon the support 3 and sustain between them a series of spools or other holders 13. In order that the number of transversely extending reinforcing filaments per unit of lengthof material reinforced may be varied within wide limits the spools or holders 13 between the several disks or other like supports rising from the hub 12 may be arranged in staggered relation. While only two series of the spools or holders 13 are illustrated in the present drawings it is to be understood that the number of disks and the number of series of spools or holders which may be sustained by the supply member, may be increased so that the number of transversely extending reinforcing filaments per unit of length on the material to be reparticularly to Fig. 7 the internally toothed gear 17 may be provided with a flanged portion 18 and be secured to the'hub portion 12 by suitable means such as the bolts 19,'the construction being such that as the shaft 4 is rotated the series of disks carrying the supply spools will be properly rotated in a plane extending at right angles to the axis of the support 3.

As hereinbefore noted the reinforcing filaments may be of any ap ropriate character ig. 4, they consist of threads or like material 20 which lead from their respective supply spools 13 delivered in continuous succession to the surface of the material to be reinforced, and to makethe action clear, it is appropriate at this time to describe the means for guiding the material or fabric to and from the reinforcing position.

Mounted in suitable frames 23, Figs. 1 and 3 rising from the supporting foundation are the guiding and delivering rolls for the material to be reinforced. Each of the frames 23 is provided with a guideway 24 for a feed roll 25 which may be appropriately adjusted by means of screw 26 toward and from its companion feed roll 27 Referring to Fig. 2 it will be noted that the axis of the feed roll 25 is mounted in the slide'box 28 which by means of the screw 26 maybe appropriately adjusted to regulate the pressure between the feed rolls 25 and 27 Mounted on the shaft of the lower feed roll 27 is a gear 29 which may be driven from any suitable-source of power as by the gear 30 on the main driving shaft 8 and through the idler 31, the construction being such that when the shaft 8 is turned the feed roll 27 and the companion feed roll 25 will be appropriately turned to feed the material or fabric a, between them. If the material or fabric a, Fig. 3 has not been previously treated with an adhesive, such adhesive may be supplied to the surface of the material or fabric a, as it passes between the rolls 25 and 27 or at any other desired location. In the present instance the frames 23 support between them a tank 32 of any 5 desired character for holding an adhesive liquid which may preferably be of water proof character. In case the surface of the material has been previously gummed the liquid in the tank 32 may be simply a moistening liquid.

Mounted for rotary movement in the frames 23 are the rolls 3435, which are similarly supported and guided for adjustment toward and from each other as arethe rolls 25 and 27. As indicated in Fig. 2 the roll 34 is mounted in a sliding box 36 which is adjustable by means of screw or other device 37, and the roll 35 is provided with a gear 38 which through idler 39 and the, idler 31 may be driven from the gear 30 on the main driving shaft 8, the construction being such that upon rotation of the driving shaft 8 the rolls 25, 27 and the rolls 34, 35 will be rotated to guide and move the material or fabric a, to and from the reinforc ing. position as will presently appear.

It may sometimesbe desirable to superpose another web of material or fabric upon the fabric a and this is indicated in Fig. 3 where the fabric or web I is taken from a source of supply and passed between the rolls 34, 35.

The reinforcing filaments or threads are to be drawn from supply spools and disdistending arms.

tightening the bolt 47.

tended transversely of the web or material to be reinforced and then delivered by such drawing and distending means directly upon the surface of the material or web to be reinforced. To effect this operation expeditiously and continuously at the desired speed the present invention contemplates that the drawing and distending means shall consist of a series of arms which while movable in a continuous path or rotated about the-axis of the support 3 shall be moved successively and progressively in a longitudinal direction transversely of the fabric to suecessively and continuously deliver filaments one after the other directly to the surface of the web or material to be reinforced.

In carrying these features of the present invention into practical effect there is provided a fixed inclined guide or directing member with which is rotatably associated an actuator for a series of drawing and In the present instance of the invention the guide or director consists of a ring 40, Figs. 2 and 4 having a guiding recess therein for the reception of the circular or ring portion 41 of the actuator 42.

.The guide or director 40 may be secured in substantially inclined position by any appropriate means, but in the present instance of-the invention said guide or director is provided with a center-supporting sleeve 43 fitted upon support 3 and secured thereto by a bolt 44, Fig. 4, the construction being such therefrom the hub portions 45, Fig. 6 for the reception of pins 46 secured to the guide or director 40, the construction being such that loosening the clamping bolt 47, the guide or director 40 may have its inclination changed with respect to the axis of the support 3 and then held in such position by Other means for incline adjustment of the guide or director 40 may suggest themselves to those skilled in the art but that herein described furnishes a good practical form of thisfeature of the invention.

Rotatably mounted upon the support 3 is an extending hub or sleeve 48 to which is secured by suitable means such as bolt 49, a gear 50 having the internal teeth 51 which are adapted to engage the teeth of gear 52, Figs. 4 and 8 secured to the shaft 4. R0- tatably mounted upon the support 3 is the hub 53 carrying the fingers 54, said hub 53 and fingers 54 being secured to the internally toothed gear 50 by suitable means,

4' that as the sleeves 48 and 53 are rotated from the shaft 4, the fingers 54 alternately engage and move the actuator 42 in its inclined circular path. The actuator 42 is preferably formed as indicated in Fig. 6 and provided with two diametrically supported slots 55 adapted to receive the operating fingers 54 as said fingers are-rotated in their circular path at right angles to the axis of the support 3. The described means for operating the actuator 42 has been found to be simple and efiicient in structure but it will be understood that the means for operating the actuator 42 in its inclined path may be variously changed within the true scope of the present invention. In order to maintain the sleeves 48 and 53in adjusted position upon the support 3 collars 56 and 57 may be employed substantially as indicated in Fig. 4, suitable set-screws 58 serving to hold the collars in adjusted position longitudinally on the support 3.

Secured to the hub 48 and preferably, but not necessarily, .cast integral is the guide 59 Fig. 4 having guiding portions 60 provided with slots through which pass the drawing and distending arms 61.

The drawing and distending arms 61 are connected by links 62 with the actuator 42, and as a preferred means to this end, each link 62 is provided with ball and socket 'oint connection 63 with the actuator 42.

he other end of the links 62 are connected with the drawing and distending arm 61 by slot and pin 64 asindicated in Fig. 4 and for a purpose that will presently appear, the construction being such that as the actuator 42 is moved in its. inclined path the connected drawing and distendin arms which rotate in unison therewith wil be reciprocated in the guide member 59. g

It is the purpose of the drawing and distending arms to draw the filaments from thesource of supply or spools 13 and distend such filaments in transverse relation with the material or web to be reinforced, and to expeditiously effect this purpose, especially where wide material or webs are to be reinforced the illustrated form of the invention shows the drawing and distending means duplicated at each side of the ma chine although of course, where narrow webs or material are to be reinforced one-- such drawing and distending means may be sufiicient. Where however, the drawing and distending means are duplicated as in the illustrated form of the invention it is necessary to provide that one of said drawing and ing arms 61 is provided with jaws to grasp and release the reinforcing filaments, and since said jaws, except as to their time of operation, may be substantially the same for 66. A spring 67 acting on the jaw member 65 normally forces the jaw member 65 toward the opposite jaw member 68 but yields sufficiently to permit the proper clamping between the jaw members of threads or filaments of different dimensions.

The jaw member 68 is provided with a shank portion 69 normall under the influence of -a spring 70 ten ing to force the jaw member 68 into open relation with jaw member 65. The shank 69 of the jaw member 68 has a locking recess 71 in which is adapted to engage the lock 72 formed as a slide. A spring 73 acting upon the lock 72 normally forcesthe lock 72 into locking engagement with the recess 71 to maintain thejaw member 68 in clamping relation with the jaw member 65. Pivotally mounted at 74 is a lock controller 75 the end of which is adapted at times to be moved in opposition to the spring 73 to force the lock 72 out of the notch'71 and permit the jaw 68 to move out of clampingrelation with the jaw 65. As indicated in Fig. 13.each of the drawing and distending arms is preferably provided with a plurality of yielding jaw members 65, two being shown inFig. 13, but it is obvious that any appropriate number may be employed, the purpose being that each drawing and distending arm may act upon a plurality of reinforcing elements 01' threads and carry them into transverse position in relation to the fabric or material to bereinforced.

The present invention in the form illustrated contemplates that the drawing and distending arms at the one side of the machine shall draw one or more threads or filaments from the supply, carry them toward the opposite side of the machine and then deliver the ends of such filaments or threads to the drawing and distending arms at the opposite side of the machine which thereupon complete the transverse drawing and, distending movement of the filaments or threads. It therefore becomes necessary for the drawing and distending arms at the supply side of the'machine to clamp the threadsor filaments in the jaws when said arms are in retracted position, then carry these toward the opposite drawing and distending arms, release the threads or filaments at this point so that the jaws of the drawing and distending arms at the opposite side of the machine may be clamped on the ends of the threads or filaments and complete the transverse movement.

Mounted on the stand 23, Figs. 4 and 11 is a jaw closer comprising a cam piece 76 connected to a rod 77 which may be appropriately secured to the framing 23, as by means of the nuts 78 threaded to the stand 77', the construction being such that when the drawlng and distending arms succesthe cam 76 and force the jaws into closed relation upon the reinforcing filaments or threads, the lock 7 2 thereupon becoming effective to hold the jaw clamped upon the filaments or threads.

When the drawing and distending arms at the supply side of the machine meet the drawing and distending arms at the opposite side of the machine, the jaws of the arms on the supply side of the machine will open and the jaws of the arms at the delivery side of the machine are closed upon the projecting ends of the filaments or threads. To effect this purpose as the drawing and distending arms move in their endless or circular path, there is mounted upon the support 3 a stand 79 having secured thereto an opener for the delivery jaws at the supply side of the machine substantially as indicated in Fig. 4. This opener comprises a cam piece 80, supported by a stem 81 adjustably secured in the stand 79 and such cam piece is provided with inclined surface 82, Fig. 10, along which rides the end 75 of the lock controller as the drawing and distending arms move in their endless or circular path. The lock controller 75 will thus be moved to the right, view Fig. 9 of the drawing, withdrawing the lock'72 and permit the jaws carried by the arms on the supply side of the machine to release the filaments or threads 20. The ends of the filaments or threads 20 extend somewhat beyond the jaws and are thereby grasped by the jaws of the arms at the opposite side of the machine when these arms meet. To effect this closing movement of the jaws at the deliv-.

hereinbefore pointed out. Thereupon the arms at the supply and delivery side of the .machine return to their outward position,

the filaments or threads slipping through the jaws of the arms at the supply s1de of the machine as the jaws at the opposite side of the machine distend the threads fully into their transverse relation with the fabric or material to be reinforced.

The threads are now in position transversely of the fabric or materialand are to be delivered thereto as indicated in Fig. 9, the jaws at the supply side of the machine, at this time, that is when the arms have been fully retracted, being again closed upon the filaments or threads as hereinbefore described.

An important feature of the present invention as hereinbefore noted is the direct delivery of the reinforcing filaments to the fabric or material to be reinforced from the drawing and distending means, as such means successively draw and distend the threads and move in their continuous or circular path. The threads should not be released from the jaws of the drawing and distending arms until after they have been placed upon the material to be reinforced and secured thereto. be a period of dwell of thedrawing and distending arms during a portion of their I continuous or circular path movement in order that they may hold the threads and dehver them to the material and release them only after the material has takencharge of them. It will now be apparent 'why the drawing and distending arms are means at the time the filaments are to be delivered to the material, each of the arms 61 is provlded with a shoulder 84, Figs. 4, 5

.and 9 which shoulders are adapted to engage the wall 85 of the guides 60 and prevent further longitudinal operating movement of the drawing and distending arms while the actuator 42 moves the links 62 against the tension of the spring 86. The length of the slot and pin connection between the links 64 and the drawing and distending arms is suflicient to permit the desired dwell in the longitudinal movement of the drawing and distending arms .as they and the actuator move in their continuous path about the axis of the support 3.

During this dwell of the drawing and distending arms it is desirable that the filaments or threads be forced into holding engagement with the'adhesive surface of the material to be reinforced and to effect this purpose there is mounted opposite the roller 35, Figs. 3 and 4, a compression roller 87. This compression roller 87 may be supported yieldingly to press toward the roller 35 There must therefore in. supports 89 sustained from the tubular pass.

member or support 3, Fig. 4 and normally under the action of a spring 90, Figs. 4 and 5, the construction being such that while the compression roller 87 may force the threads yieldingly upon the surface of the fabricpassing about the roller it may yield to permit different thicknesses of threads to This action of the compression roller 87 takes place while the drawing and distending arms 61 dwell in their longitudinal movement already described and are moved in their continuous ath about the support 3. The filaments or threads having now been placed upon the material to be reinforced they are released from the drawing and distending arms to permit them'to pass along with the reinforcing material. This release at the delivery or right-hand side of the machine indicated in Fig. 9 is effected byan opening movement of the jaws caused by the cam 80 acting on the locking controller 75. The release of the filaments or threads from .the drawing and distending arms at the supply side of the machine is effected by a cutter which cuts the filaments or threads a short distance beyond the jaw or said arms after said jaws have been clamped upon the filaments or threads.

The cutter mechanism may be variously contrived to effect the purpose but a good toward and from the roller 35.

' perforce form thereof is indicated in Figs. 9 and 12 wherein the compression roller 87 is pro vided with recess 91, Fig. 9, into which projects a pin 92 adapted to engage a pin 93 projecting from a cutterdisk 94. The cutter disk 94i has a cutting edge 95 and is rotatably mounted in a carrier 96. Said carrier 96 has an opening 97 centrally thereof which embraces a bearing portion 98 of the support 88 for the compression roll 87. The opening 97 is elongated as indicated in Fig. 12 to permit the cutter carrier 96 to move To effect this movement and cause the edge of the circular cutter to cut the filaments or threads as they pass between the compression roller 87 and the roller 35 the said cutter carrier is provided with a projecting arm 99, Fig. 9 pon which is seated one end of spring 100, the other end of spring finding a seat against collar 101 on the support 88, the construction being such that the cutter carrier96 and the cutter 94. will be yi'eldingly pressed toward the roller 35 and serve to cut the filaments. between the jaws of the drawing and distending arms at the supply side of the machine and-the edge of the fabric being reinforced, quite regardless of whether such fabric and threads are more or less thick or thin.

g It mayibe desired at times to introduce mounted in the stands'23 a guide roll 102 about which these longitudinal threads may be guided to and about the compression roller 87, said longitudinal threads or,fila-. ments preferably being introduced at the bite between the rolls 87 and 35.

From the construction described as on good practical form of the invention it will be apparent to those skilled in the art that the present invention provides a machine for reinforcing fabrics or materials such as paper or the like by introducing transverse reinforcing filaments directly to the material to be reinforced from the drawing and distending means; and it will be further noted that the present invention provides drawing and distending means which continuously and progressively draw from a source of supply the reinforcing filaments, progressively distend them transversely of the material to be reinforced and delivers such transversely distended filaments successively to the material to be reinforced.

In a machine of the character de scribed, the combination of rotatable means for holding a series of reinforcing filaments, a series of drawing devices at each side of the machine, means formoving the series of drawing devices in an endless path substantially parallel to the plane of rotation of the said holding means, means, for moving the drawing devices at each side of the machine toward and from each other and means for transferring filaments drawn from the holding means by one set of drawing means to the control of the drawing means at the other side of the machine.

22. In a machine of the character de scribed, the combination of rotatable means for holding a plurality of reinforcing filaments, a series of arms at opposite sides of the machine movable bodily' in a path sub.- stantially parallel to the plane of rotation of the holding means, and means for successively moving the arms at opposite sides of the machinetoward and from each other to i draw and distend filaments transversely of the material'to be reinforced.

23. In a machine of the character described, the combination of rotatable means for holding a plurality of reinforcing filaments, a series of arms at opposite sides of the machine movable bodily in a path submaterial, the combination of means for conor distending members mounted for bodily movement in a curved path, and means for moving said drawing or distending members progressively toward and from each other in a direction substantially at right angles to the bodily movement of said members for drawing or distending reinforcing filaments into transverse relation with the material to be reinforced;

25. In a machine for reinforcing paper material, the combination of means for con-' drawing or distending reinforcing filaments into transverse relation with the material to be reinforced, and means for transferring the reinforcing filaments from said members to the material to be reinforced.

26. In a machine for reinforcing paper material, the combination of means for continuously feeding the material to be reinforced in a longitudinal direction, opposed sets of drawin or distending members mounted for bo ily movement in a curved path, means for moving the drawing or distending members of said opposed sets progressively in a direction substantially at right angles to the bodily movement of said members for drawing or distending reinforcing filaments into transverse relation with the material to be reinforced, and means for pressing the distended reinf0rcing filaments into contact withthe material to be reinforced.

In testimony whereof, I have signed my name to this specification.
